To all whom it'ma z concern: a ie it known that I, lVILLIAM A. E. HEN-nicnacitizen ofthe United States-residing at Boston, county of Suffolk,and State of lylassachusetts, have invented an Improvement inReversing"Mechanism, of which the-following description, in connectionwith the accompanying drawing, is a specification, like letters on thedrawing represent ing like parts. I

This invention relates to reversing meetainsm, and has for its object toprovide a novel 3 reversing IIlGCllHIllSIH by which the direction ofmovement of a driven member may be quickly and instantly reversed atanydesired predetermined times. i

The invention comprises a reversmgmechanlsin and a controller thereforwhich 1s 'arranged to control the time of the reversing action, and-thiscontroller is preferably actuated by a time mechanism which "can beadjusted so as to render the controller active to cause ,a'reversal ofthe movement at different statedperiods of time.

One embodiment of my invention is shown in thedrawi-ngs and will firstbe described, and then the novel features of the invention will bepointed. out in the appended'claims. I

of the time mechanism for reversing the clutches.

My improved reversing mechanism :is:

adapted to be used with a great-variety of machines where it-isnecessary to reversethe direction of motion of a driven element atstated periods of tnne.

? I have herein shown :myinvention asinterposed between a rotary drivingshaft and a rotary driven element, although it will be understood that:the nature of the driven element, whether a rotary ora-reciprocatingelement, does-not affect in. any Way the in is illustrated as a wormgearxand is driven by a worm 7 carried by a driven shaft '8.

The particular form of driven member and manner of gearing it to thedriven shaft 8 is 'not'essential, however. i Referring now to Fig. 6 inwhich the arrangement of the clntchmechanism for connecting the twoshaft-s Band 8 is illustrated,

it will be observed that the shaft 3 has :fast

thereon a sprocket-wheel 9 over which runs a sprocket-chain 10 thatconnects said wheel 9 to another sprocket-wheel :11 loose on the shaft8. Loose on thesh-aft 3 is a gear wheel 12 which meshes with agear 13fast on the shaft '8. The sprocket-wheel land the gear 12 are adapted tobe connectedby a suitable clutch 14, and similarly the gear 13 which isfast on "the-shaft B and the sprocket 11 which is loose thereon areadapted to be connected by a suitable clutch 15. The clutches 14 and 15may be of any suitable construction, but I prefer forl-many reasons toemploy the clutch shown in PM- ent No. 840,847, dated January 8, 1907,and

this is the type'of clutchillu'strated in the present drawing. Thisclutch is a friction clutch in which one clutch'member is in the be usedwithout form of a friction coil, and the other in the form of a frictiondrum which is encircled by the coil. The two clutches 141 and are alikein every respect and each comprises a friction drum 16 about which iscoiled a friction coil 18. Each friction coil has its ends fast to twocollars 21 loosely mounted on the corresponding drum 16, and is inclosedby a housing 19. The housing 19. of the clutch 14 is fast to the shaft 3and it has a hub to which the sprocket-wheel 9 is fast, and the drum 16of said clutch is loose on the shaft 3. The housing of the clutch 15 isloose on the shaft 8 and has a hub 20 to whiclrthe sprocket-wheel 11 isfast, while the drum 16 of said clutch is fast to said shaft 3 and hasfast thereto the gear 13. i

Each clutch is thrown into operation by turning the collars 21 thereofin opposite directions, thereby to tighten the coil 18 about the drum. 5This turning of the collars in opposite directions is accomplished bymeans of a clutch actuator 22 which is fast to a clutch-sleeve 23mounted on the shell 19 for longitudinal movement. Each clutchsleeve isshown as having a groove 2 1 therein to receive a fork by which theclutch-sleeve is shifted longitudinally. To avoidconfusion, however,Ihave designated the fork of the clutch lat by the reference numeral 25,and that of the clutch 15 by the reference numeral 26.

Suffice it to say that when either of the clutclrsleeves 23 and theconnected actuator "22 are moved to the left Fig. 6, the correspondingclutch is thrown into operation and when they are moved to the right,the clutch is released. As the parts are shown in Fig. 6, therefore, theclutch 14 is in operation, and the clutch 15 is loose or is inactive,and the gear 12 is therefore clutched to the driving shaft 3, while thegear 13 is loose from the sprocket-wheel 11. The rotation of the drivingmember 3 is communicated through the clutch 14L to the gear 12, and saidgear 12 rotates the gear 13 which is fast to the shaft 8, the rotationof said shaft being permitted because the clutch 15 is inactive. Withthe arrangement shown in Fig. 6, therefore, the driving shaft 3 drivesthe driven shaft 8 through the clutch 1st, and the two shafts rotate inopposite directions. If the clutch 14L is released or rendered inactiveand the clutch 15 is clutched or thrown into operation, then thesprocket-wheel 11 and the gear 13 will be clutched together by saidclutch 15, and the shaft 8 will be driven from the shaft 3 through thesprocket wheels 9, 11 and the clutch 15, and said shaft 8 will be drivenin the same direction as the shaft 3. i

The mechanism for shifting the clutches herein illustrated comprises asuitable actuator which is adapted to be brought into engagement withthe forks of'either or both clutches at the proper time to shift saidforks and consequently the sleeves-23 in the proper direction.

The forks 25 and 26 are mounted on rods or guides 27 and 28, and areprovided with projections or noses 29 and 30, respectively, see Figs. 8and 9. Situated between the noses are two sliding actuators 31 and 32,see Fig. 1, and these actuators have associated with them sliding bolts33 and 3%, respectively, said bolts being mounted for movementtransversely of the slides. The bolts normally stand within the limitsof the sliding actuators, but they may be thrown out transverselythereof in one direction or the other into position so that the endsthereof will engage the noses 29 and 30 to shift the clutches as theactuators are reciprocated. The bolt 34: acts to throw the clutches intooperation and for convenience I will refer to it as a knock-in bolt; Thebolt 33 actsto throw the clutches out of operation and for convenience Iwill refer to it as a knockout bolt.

Referring now to Figs. 8 and '9, the full lines show the position of theforks 25 and 26, and their projections 29 and 30 when the parts are inthe position shown in Fig. 6, and in this figure the bolts 3 1 and 33are thrown out in opposite directions so that the projections 29 and 30stand in the path of movement of said bolts as the actuators 31 and 32are reciprocated. When the bolts are thus thrown out, as shown in Fig.8, it will be seen that the movement of the actuators to the right willshift the fork 25 into the dotted line position, thereby disengaging orrendering idle the clutch 1 1, and the movement of the actuators to theleft will shift the fork 26 into the dotted line position, therebythrowing the clutch 15 into operation, thus causing a reversing of thedirection of rotation of the shaft 8. If when the forks are in thedotted line position Fig. 8 or the full line position Fig. 9,'a nd thebolts 33 and 34- are thrown out in. the opposite direction, or as shownin said Fig. 9.

and the actuatorsware reciprocated, "it will 1 be seen that the forkswill be shiftedinto the dotted line position Fig. 9 or the full linecrank-shaft 36 which" is suitably journaled in the frame. Said shaft 36has thereon a worm-gear 37 that meshes with and is driven by a worm 38fast on the driving shaft 3. The actuator 32, therefore, is operateddirectly from the driving shaft 3. The actuator 31," on the other hand,is operated from the driven member 5, and for this purpose, I have shownsaid actuator as having rising therefrom at one end an arm 39 having aroll 40* adapted to be'engaged by a cam 41 carried by the driven member5.

The cam 4L1 by engaging the roll elO moves the actuator 31 to the right,Fig. 1, and said actuator is returned to its normal position by suitablesprings 42, see Figs. 2 and 16.

The actuator 32 is that which throws the clutches into operation whenthe bolts are properly adjusted, and the actuator 31 is that whichthrows the clutches out of operation. It will be seen, therefore, thatthe actuator which throws the clutches into op eration derives itsmovement directly from the driving member, while the actuator whichthrows the clutches out of operation derives its movement from thedriven member.

designated .43, and 44:,IQSDGClZlV6ly.

45 and L6 designate projections, the lower ends of which are received inthe grooves 4:3 and 44, respectively, and which depend from two slidest? and 48 that are slidably mounted in a cap or bridge-piece 4C9. Saidprojections extend through slots '50 andiel in the actuator 31, saidslots permitting the actuator to be reciprocated without interferingwith the movement of the slides. The connection between the projections45 and t6 and the bolts is such-as to permit the bolts to move with theactuators with out withdrawing the projections from the grooves 43 and.44.

52 designates a T-shaped lever pivoted to the bridge-piece and havingtwo arms 53 and 5-1 which engage the slides l? and 4:8. The third arm ofsaid lever is connected by a link 55 with an arm 56 secured to anoscillating shaft '57 (see Fig. 22). This shaft 1s adapted to beoscillated in either direction, thereby to turn the T-lever 52 in eitherdirection from its central position shown in Fig. 16. In the positionshown in Fig. 16, the bolts 33 and 34 are in their normal position, bothstanding within the limits of the actuator, but by swingingthe T-leveriii-one direction or the other, the bolts may be thrown either into theposi-. tion shown'in Fig. 8 or into that shown in Fig. 9.

.The connection between the arms and 5.4. of the T-lever 52 and theslides 47 and 48 is preferably a yielding connection for reasons whichwill be more fully hereinafter explained. To obtain this yieldingconnection, l iave shown the ends of each of the arms o3 and 54 asconfined between two yielding members, shown as pins 58, see Fig. 16,each of said members being racked by a suitable spring 59. The springsare of such a strength that under ordiary conditions, the turning of thelever 02 will not compr ss them but will instead move the slides t? and48, thereby to shift the bolts 33 and If, however, either bolt shouldmeet an obstruction, the corresponding spring will yield and thus permitthe lever 52 to be thrown without brcaliing any of the parts.

The means I have herein illustrated for governing the operation of thecontroller and thereby governing the times at which the reversing actionwill take place is in the nature of a time mechanism ,which can beadjusted to cause a reversal to take place at any predetermined time,that is, after the driven member 5 has made any predetermined number ofrevolutions. The time mechanism herein illustrated will now bedescribed.

.Fast on the shi t are two arms 60 and Glavhich are adapted to beactuated alternately by a suitable cam member slidably mounted on ashaft This cam member has a long screw-threaded hub (3 l- (see Fig.

nut 65, and said hub has splined thereto a gear-wheel 66 that mesheswith and is driven by a gear 67 fixed to the driven member 5. Frcn thisconstruction it will be seen that the rot ,on of the gear 66 will resultin screwing the hub 6i through the nut and thus both rotating the cammember 62 and advancing it along the shaft 63. This can" member 62 hason each face a spiral cam shoulder 68 which is so arranged that as thecam is rotated and ad'anced to the left Fig. 17, for instance, the camsurface 68- on the left hand side of said disk will engage the end ofthe lever 61 and thereby rock the shaft 57 into the dotted line positionFig. 23, thus causing the T- lever to be turned into position toproje'ct the bolts 33 and 34: into the position shown in Fig. 9, wherebya reversal of the direction of rotation of the driven member willtakeplace as abore described. This reversal ofthe direction of rotationof the driven member obviously causes a reversal in the direction ofrotation of the cam (32 and its connected hub (i l, and said cam (32then moves to the right 1'? until the cam-shoulde" (38 on the right-handside of the d n: engages the lever 60 when said lever 60 will bethrowi'i into the full line positions Fig. 23,'thereby causing the T-cmistuction so as to insure the shown in Fig. 8. This will result inshift ing the clutches to again reverse the direction of rotation of thedriven member 5.

In the present OIHlJOCllIHQDi} of my invention, the gear (3? is amutilated. gear, so that the hub bet is rotated intermittently andduring a portion only of the rotation of the driven member 5. The lengthof the gear 67 however is such that the gear (36 is rotated once duringeach rotation of the gear (37. I employ this coi'istruction so that themovement of the cam disk 62 when it moves will be comparatively rapid,thus causing a. quick reversal of the clutches.

After the shaft 5? has been turned in either direction, thereby tooperate the lever the parts are immediately restored to their normal orneutral position, as shown in Fig. 1., by the movement of the actuator31.. For this nn-pose, the projection it; has thereon a fin (380, andthe slot 51 is provided with a narrow extension 39 which is connectedwith the wider portion ther f by inclined surfaces 72 (see Fig. 1G). iththis construction, it will. be seen that the movement of the actuatorLil. to the left, l i 1 and 16, will center the slide ltS by the c.gement of one of the inclined surfaces 72 .th the in (180, thuswithdrmving the bolt 5-34: and throwi ng the 'l lever 52 into itscentral position, as shown in llig. l6, this o ieration also re sultingin withdrawing the bolt 7 The normal position of the act ator 3]. is tothe left with the fin 80 occu 'iying the groove 69, and therefore theslide {to a its projection 4:6 are normally locked against movement bysaid fin (380. and said slide released only when the actuator 31 is 1-o'ved forwardly or into the position shown in Figs. 1 and 16 by the cam41, and this occurs only when the driven n'iember is in a predeterminedposition.

nil

I have adopted this versal of the mechanisn'i only when the dri her 5 isin a predetermined position.

tion while the slide 31. is in its norma l. p tion to the left, thelever will be turned and the slide t? moved to project the lcnocle outbolt 2}?) outwardly. The lmoclz-in bolt ll. however, is not projected asthe slide 48 is locked, and therefore the reversing operation does nottake place until the slide 81 is thrown into the position shown in.Figs. 1 and 1.6 by the cam 4:1 which occurs when the driven member is inits predetermined position. The movement of the actuator 31 to theright, as shown in Fig. l, bri 's the projected end of the lniocleoutbolt 53 into on gagement with the nose of the corresponding forl: andreleases the clutch which active or in operation, and as soon, as theactuator 31 has been moved sulliciently to release the [in (380, theslide l-8is operated, by

its springs 59, thereby to project the knock- If the shaft 5? operated in either direcin bolt 34:, and the latter is brought against the otherfork by the reciprocating of the actuator 32, thereby throwing the otherclutch into operation. It will thus be seen that the reversal can onlybe done when the driven member 5 is in a predetermined position.

lin order. to make the timing mechanism capable of reversing atdifferent stated periods of time, i have adjustably mounted the arm onthe shaft 57 so that said arm may be placed at different distances fromthe arm 60. For this purpose, the arm 61 is shown as having a hub 70which is slidably mounted on the shaft 57, but which may be locked inposition on the shaft by means of a pin 71 which adapted to enter anyone of a number of holes 720 in the shaft, see Fig. 17. The hub G4; isprovided with two spaces 73 having no screw-threads, and-the shaft 63has thereon at each end acushion or spring 74. This construction isadopted so that when. the hub 64: has been advanced to its maximumdistance either to the left or to the right. Fig. 17, one of the smoothportions Y3 thereof will come opposite the screwihreads in the nut 65,and either the disk 62 or the end. of the hub 64 will engage andcompress one of the springs 74. When the parts have reached either oneof these posi" ti ons the hub will not be advanced any further, eventhough the rotation thereof continues.

'lhe springs 74 are for the purpose, of throwing the screw-threads onthe hub and the nut into engagement immediately upon the reversal of thedirection of rotation if, just previous to reversal, the hub has beenscrewed entirely out of the nut in either direction. In addition tothese features, I have provided a manually-controlled device forstopping the driven element or for causing it to continue its rotationindefinitely without reversal in either direction.

Heft-airing now to Figs. 7, 10 and 11, it will be seen that the slides4t? and 4L8 have formed on their upper sides transverse grooves 75 and76, respectively. Situated above the slides and movably mounted in thebridge or head 49 is a starting-and-stoppi: f: slide 77 from whichdepends pins 7 51, T9 and 80. The slide 77 has connected there to a rod81 which is connected to a manuallyecntrollable lever 82 by which saidslide is operated.

l i hen the starting-andstopping slide is in its normal position, asshown in Fig. 11, the slides t? and 48 can be moved freely. When theslide 77 is moved to the right into the full, line position Fig. 10, thepin 79 enters the 'roove 76 in the slide &8, and thus locks said slidefrom movement and holds it in its central position, and the pin 78passes clear through the groove 75 in the slide 4:7

and therefore does not interfere with the free movement of'the saidslide 47. Vhen, the said st'arting-and-stopping slide is moved, into thecentral position shown in dotted lines Fig. 10, the pin 78 enters thegroove 7 5 in the slide 17, and the pin 80 enters the groove 7 6 in theslide 18. When the'parts are in this position, both of the slides 417and 41-8 are locked from movement in either direc tion.

Whenit is desired that the mechanism should run normally, and reverseitself at stated intervals of time, the starting-and shown in Fig. '11,thereby to release the slides 17 and 4C8, so that they'can have'freemovement ineither direction. When it is desired that the machine shouldrun continuously in one direction without reversing, thestarting-and-stopping slide is when these slides are thus locked,neither clutch can be operated, and as a result the mechanism will runwithout reversing hen it is desired to stop the mechanism,

the startin -and-sto i11 slide 77 is moved e PP b into the right-handposition,-as shown in full lines Fig. 10, in which position the slide 48is locked, while'the slide 17 is free for movement to disengage orrelease the clutch which is in operation. The lever 82 for operating thestartingand-stopping slide works in connection with a quadrant 83,provided with notches adapted to hold the lever in any one of its threepositions. i

It is often desirable to bring the mechanism with which this reversingmechanism may be used to rest instantly, whenever both clutches aredisengaged, and to accomplish this I have provided a brake mechanismwhich is normally inactive, but which is rendered active to instantlystop'the mechanism whenever both clutches are released.

The brake mechanism herein shown comprises a brake-band 8 1, which islocated within a hub or flange 85 formed on the gear 13. It will beremembered that said gear 13 is fast to'the shaft 8. 7 The brake is setby expanding the brake band outwardly against the flange 85, suchexpanding operating to apply sufficient friction 'to the flange to bringtheshaft 8 to rest and hold it in such position. The two ends of thebrake-band 84 are connected to two independently-movable sliding members86, 87 (shown in dotted lines Fig. and each of said sliding membershas asocket or recess inwhich is received one of two projections 88carried bya brake actuator 89. This latter has connected thereto a rod 90 which inturn is connected to an arm of a rock-shaft 91. This rock-shaft 91 hasfast thereto an arm 92 to which is'connected a member that leads to thelever 82. 1 :The connectionbetween the lever .82

the arm 92 is a yielding connection, so that said lever may be operatedwithout causing the brake to be applied until both clutches arereleased. For this purpose, the member 93 is made in two sections whichtelescope together, and are yieldingly maintained in their properrelative positions by means of a spring 94. The member 93 also has apinand-slot connection with lever 82, said lever for this purpose havingan arm 95 extending therefrom provided with a pin 96 that enters I aslot 97 in the end of member 93. stopping slide 77 is moved into theposition It is necessary that the brake should not I beapplied exceptwhen both clutches are released, and I have therefore provided a lock ifor normally holding the brake inoperative, jwhich lock is releasedautomatically to per- Zmit the brake to be applied only when bothTclutches are released.

moved into the dotted line position, Fig. 10, i thereby to lock both theslides 17 and 18, for,

Referring now to Figsf and 16, it will to cooperate with a camprojection 102 on the end of a slide 103 (one end of which is shown inFig. 19), which is mounted in a groove in the actuator 31, and isadapted to move transversely thereof (see Fig. 1).

. This slide'103 has on its upper face a groove 104 in which is receiveda fin 105 on the underside of a sliding member 106 that is mounted toslide transversely in the bridge or cover 459.

The sliding member 106 has at one end a V-shaped groove 107 in which isreceived a projection 108 (see Fig. 22) formed either on the end oflever 56, or on the end of the link 55.

WVhen the parts are in their normal position, as shown inFigs. 1 and 22,the projection 108 stands at the apex of the groove 107, and the slidingmember 106 and consequently the slide 103 are in their withdrawnposition'in which position the cam projection 102 is outof line with thecam projection 101 on thelocking latch, so that the reciprocatingmovement of the slide 103, due to the movement of the actuator 31 doesnot release the locking latch 99. When, however, the shaft 57 is turnedin either direc tion by the cam 62, thereby to set the clutchreleasingand clutch-engaging mechanism, the sliding member 106 is carriedforwardly, thereby throwing the projection 102 into line with'the camprojection 101, and whenthe parts have assumed this position themovement of the'actuator 31 to cause the release of either clutch, liftsthe locking pawl 99 out of engagement with the arm 98.

The rock-shaft 91 has fast thereto a weighted arm 167, wh h9 i unresrained,

would tend to set the brake. The length of the connection 93 is suchthat when the lever 82 is in its central position, as shown in Fig. 1,which is the position of the lever when the machine is runningcontinuously in one direction, the spring 94; will be under sufficienttension to counterbalance the weighted arm 167 so that even if the loclr99 is released the brake will not be applied.

l When the lever 82 is thrown into its right hand position, Fig. 1,which is the position occupied by it when the machine is runningnormally and reversing at'stated periods, the spring 9 1 is placed understill greater tension, aS will be obvious, and in this condition it morethan counterbalances the weighted arm 167. So long therefore as thelever 82 is in either the central or right hand position, Fig. 1, thebrake cannot be applied even though the locking latch. 99 is released.hen, however, the lever 82 is thrown to the left hand position, Fig. 1,which is the position when it is desired to stop the machine, thetension on the spring 9 1 will be relieved and the pin 96 will move downto the right hand end of the slot 97.

The latch 99 is then theelcment which holds the brake from beingapplied. When the parts haveassumed this position the machine will rununtil the clutch is released and the slide 103, projected outwardlythereby to release the locking latch 99 by the re ciprocating movementof the actuator 31. When this occurs the weighted arm 1.07 comes intoplay to apply the brake and stop the parts instantly.

In order to prevent the brake from being set before the clutch isreleased when it is desired to stop the machine, it is desirable toprovide means for preventing the stopping-and-starting slide 77 frombeing thrown to the right or into the full line position Fig. 10, exceptwhen the slide 31 is in its normal. position to the left with the roll10 against the low portion of the cam -11. To accomplish this object, Ihave provided a lock 200 which is slidably mounted in the bridge piecel9, and is provided at its lower end with a cam surface 201. This lockis yieldingly held against the slide 31 by means of a spring 202 (seeFig. 1) and is provided in one side with a notch 203 (see Figs. 12 and13). The end of the stopping-andstarting slide 77 is provided with a rib20 1 adapted to pass through the notch 203 when the lock 200 is properlypositioned.

When the lock is in the position shown in Fig. 1, which is that shown indotted line position Fig. 13, the notch 203 is out of line with the rib2041- and it will be impossible, therefore, when the parts are in thisposition to move the stopping-andstarting slide 77 to the right or intothe full line position Fig. 10. When, however, the cam 41 is turned soas to permit the slide 31 to be moved into its normal position to theleft, the cam surface 205 upon the slide engages the cam surface 201 onthe lock and raises the latter to bring the notch 2 03 therein oppositethe rib 20a on the stopping-and-starting slide 77 so that when the slide31 is in its position to the left Fig. 1, the slide 77 is free to bemoved to the right to stop the machine.

I have provided a frictional connect-ion between the cam 11 and the gear5 so as to get what amounts to a longer dwell on said cam. As shown inFigs. 1, 2 and 14, the shaft 6 has fast thereto a plate member 200provided with a nose 207. This plate lIlQIl'lo er is provided with a hub208 on which the cam 11 is loosely mounted, and the cam bears againstfriction blocks 109 carried in the driven member 5. i

110 represents a spring plate retained in position by a screw 111 andadapted to bear against friction blocks 112 that are received inapertures in the plate 206 and bear against the outer face of the cammember 41. Said cam member is provided with two stops or projections 113against one of which the nose 207 is adapted to abut, as shown inFig. 1. The parts are shown in Fig. 1 in the position they occupy whenthe cam is moving in the direct-ion of the arrow .9. The reversing ofthe mechanism will always take place when the roll 410 is bearingagainst the low portion of the cam 11, that is, when the slide 31 is inits position to the left Fig. 1, and when the reverse takes place thecam l1 will remain stationary until the plate 206 which is fast with theshaft turns sufficiently to bring the nose 207 against the projection113 when the movement of the cam 11 is taken up and it then rotatesuniformly with the driven member.

I have also shown thrust-collars 120 against which the ends of the worm7 are adapted to bear, said collars being preferably provided withanti-friction bearings. These thrust-collars are for the purpose oftaking the end-thrust in the shaft 8. 121 is a hand wheel secured tothe-shaft 8 by which the parts may be adjusted or turned if desired.
